    toshiba z835 no backlight

    hi, there is no backlight on my led screen, I replaced screen but it`s the same. I can`t find diagram for this laptop and can`t identify component marked with 303. I think is a fuse but not sure. Some one help?
    Thanks.

      If it's fuse, just use thin wire, thin as hair.

              Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
              by HTR-Informatique
              Hello,

              YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

              I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

              On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

              I also changed the screen because the PC fell and the screen was broken.

              I changed the battery with a new and original battery.

              I also had corrosion/oxidation on the...

              Hisense 40H4F no backlight but turns off after splash screen
              by frannyjunk
              So I have this Hisense tv where the backlight does not come on. But when it is turned on, when I shine a flashlight on the screen, I can clearly see the splash screen then it turns off. I looked at the mainboard and was expecting to see bulged capacitors, but they all look fine. I unplugged the backlight from the mainboard, and get the same symptoms (i.e. no backlight, dark splash screen then just a black screen). Is this just a backlight issues? Do Hisense tvs turn off by itself if the backlights are unplugged or are bad? Or is this a mainboard issue?

              TIA.

              AOC U34G3XM, new monitor, black screen with backlight on, possible shortcircuit during dissassembly
              by turmix
              Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.

              The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
              At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine

              During another reassembly, I made a mistake, and...

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
